I. From the account which Paul gives of what passed between him and the other apostles at Jerusalem, the Galatians might easily discern both the falseness of what his enemies had insinuated against him and their own folly and weakness in departing from that gospel which he had preached to them. But to give the greater weight to what he had already said, and more fully to fortify them against the insinuations of the judaizing teachers, he acquaints them with another interview which he had with the apostle Peter at Antioch, and what passed between them there, Gal. 2:11-14. Antioch was one of the chief churches of the Gentile Christians, as Jerusalem was of those Christians who turned from Judaism to the faith of Christ. There is no colour of reason for the supposition that Peter was bishop of Antioch. If he had, surely Paul would not have withstood him in his own church, as we here find he did; but, on the contrary, it is here spoken of as an occasional visit which he made thither. In their other meeting, there had been good harmony and agreement. Peter and the other apostles had both acknowledged Paul’s commission and approved his doctrine, and they parted very good friends. But in this Paul finds himself obliged to oppose Peter, for he was to be blamed, a plain evidence that he was not inferior to him, and consequently of the weakness of the pope’s pretence to supremacy and infallibility, as the successor of Peter. Here we may observe,

1. Peter’s fault. When he came among the Gentile churches, he complied with them, and did eat with them, though they were not circumcised, agreeably to the instructions which were given in particular to him (Acts 10:9-16), when he was warned by the heavenly vision to call nothing common or unclean. But, when there came some Jewish Christians from Jerusalem, he grew more shy of the Gentiles, only to humour those of the circumcision and for fear of giving them offence, which doubtless was to the great grief and discouragement of the Gentile churches. Then he withdrew, and separated himself. His fault herein had a bad influence upon others, for the other Jews also dissembled with him; though before they might be better disposed, yet now, from his example, they took on them to scruple eating with the Gentiles, and pretended they could not in conscience do it, because they were not circumcised. And (would you think it?) Barnabas himself, one of the apostles of the Gentiles, and one who had been instrumental in planting and watering the churches of the Gentiles, was carried away with their dissimulation. Here note, (1.) The weakness and inconstancy of the best of men, when left to themselves, and how apt they are to falter in their duty to God, out of an undue regard to the pleasing of men. And, (2.) The great force of bad examples, especially the examples of great men and good men, such as are in reputation for wisdom and honour.

2. The rebuke which Paul gave him for his fault. Notwithstanding Peter’s character, yet, when he observes him thus behaving himself to the great prejudice both of the truth of the gospel and the peace of the church, he is not afraid to reprove him for it. Paul adhered resolutely to his principles, when others faltered in theirs; he was as good a Jew as any of them (for he was a Hebrew of the Hebrews), but he would magnify his office as the apostle of the Gentiles, and therefore would not see them discouraged and trampled upon. When he saw that they walked not uprightly, according to the truth of the gospel—that they did not live up to that principle which the gospel taught, and which they had professed to own and embrace, namely, that by the death of Christ the partition-wall between Jew and Gentile was taken down, and the observance of the law of Moses was no longer in force—when he observed this, as Peter’s offence was public, so he publicly reproved him for it: He said unto him before them all, If thou, being a Jew, livest after the manner of the Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews? Herein one part of his conduct was a contradiction to the other; for if he, who was a Jew, could himself sometimes dispense with the use of the ceremonial law, and live after the manner of the Gentiles, this showed that he did not look upon the observance of it as still necessary, even for the Jews themselves; and therefore that he could not, consistently with his own practice, impose it upon the Gentile Christians. And yet Paul charges him with this, yea, represents him as compelling the Gentiles to live as did the Jews—not by open force and violence, but this was the tendency of what he did; for it was in effect to signify this, that the Gentiles must comply with the Jews, or else not be admitted into Christian communion.

II. Paul having thus established his character and office, and sufficiently shown that he was not inferior to any of the apostles, no, not to Peter himself, from the account of the reproof he gave him he takes occasion to speak of that great fundamental doctrine of the gospel—That justification is only by faith in Christ, and not by the works of the law (though some think that all he says to the end of the chapter is what he said to Peter at Antioch), which doctrine condemned Peter for his symbolizing with the Jews. For, if it was the principle of his religion that the gospel is the instrument of our justification and not the law, then he did very ill in countenancing those who kept up the law, and were for mixing it with faith in the business of our justification. This was the doctrine which Paul had preached among the Galatians, to which he still adhered, and which it is his great business in this epistle to mention and confirm. Now concerning this Paul acquaints us,

1. With the practice of the Jewish Christians themselves: “We,” says he, “who are Jews by nature, and not sinners of the Gentiles (even we who have been born and bred in the Jewish religion, and not among the impure Gentiles), knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we ourselves have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law. And, if we have thought it necessary to seek justification by the faith of Christ, why then should we hamper ourselves with the law? What did we believe in Christ for? Was it not that we might be justified by the faith of Christ? And, if so, is it not folly to go back to the law, and to expect to be justified either by the merit of moral works or the influence of any ceremonial sacrifices or purifications? And if it would be wrong in us who are Jews by nature to return to the law, and expect justification by it, would it not be much more so to require this of the Gentiles, who were never subject to it, since by the works of the law no flesh shall be justified?” To give the greater weight to this he adds (Gal. 2:17), “But if, while we seek to be justified by Christ, we ourselves also are found sinners, is Christ the minister of sin? If, while we seek justification by Christ alone, and teach others to do so, we ourselves are found giving countenance or indulgence to sin, or rather are accounted sinners of the Gentiles, and such as it is not fit to have communion with, unless we also observe the law of Moses, is Christ the minister of sin? Will it not follow that he is so, if he engage us to receive a doctrine that gives liberty to sin, or by which we are so far from being justified that we remain impure sinners, and unfit to be conversed with?” This, he intimates, would be the consequence, but he rejects it with abhorrence: “God forbid,” says he, “that we should entertain such a thought of Christ, or of his doctrine, that thereby he should direct us into a way of justification that is defective and ineffectual, and leave those who embrace it still unjustified, or that would give the least encouragement to sin and sinners.” This would be very dishonourable to Christ, and it would be very injurious to them also. “For,” says he (Gal. 2:18), “if I build again the things which I destroyed—if I (or any other), who have taught that the observance of the Mosaic law is not necessary to justification, should now, by word or practice, teach or intimate that it is necessary—I make myself a transgressor; I own myself to be still an impure sinner, and to remain under the guilt of sin, notwithstanding my faith in Christ; or I shall be liable to be charged with deceit and prevarication, and acting inconsistently with myself.” Thus does the apostle argue for the great doctrine of justification by faith without the works of the law from the principles and practice of the Jewish Christians themselves, and from the consequences that would attend their departure from it, whence it appeared that Peter and the other Jews were much in the wrong in refusing to communicate with the Gentile Christians, and endeavouring to bring them under the bondage of the law.

2. He acquaints us what his own judgment and practice were. (1.) That he was dead to the law. Whatever account others might make of it, yet, for his part, he was dead to it. He knew that the moral law denounced a curse against all that continue not in all things written therein, to do them; and therefore he was dead to it, as to all hope of justification and salvation that way. And as for the ceremonial law, he also knew that it was now antiquated and superseded by the coming of Christ, and therefore, the substance having come, he had no longer any regard to the shadow. He was thus dead to the law, through the law itself; it discovered itself to be at an end. By considering the law itself, he saw that justification was not to be expected by the works of it (since none could perform a perfect obedience to it) and that there was now no further need of the sacrifices and purifications of it, since they were done away in Christ, and a period was put to them by his offering up himself a sacrifice for us; and therefore, the more he looked into it the more he saw that there was no occasion for keeping up that regard to it which the Jews pleaded for. But, though he was thus dead to the law, yet he did not look upon himself as with law. He had renounced all hopes of justification by the works of it, and was unwilling any longer to continue under the bondage of it; but he was far from thinking himself discharged from his duty to God; on the contrary, he was dead to the law, that he might live unto God. The doctrine of the gospel, which he had embraced, instead of weakening the bond of duty upon him, did but the more strengthen and confirm it; and therefore, though he was dead to the law, yet it was only in order to his living a new and better life to God (as Rom. 7:4, 6), such a life as would be more agreeable and acceptable to God than his observance of the Mosaic law could now be, that is, a life of faith in Christ, and, under the influence thereof, of holiness and righteousness towards God. Agreeably hereunto he acquaints us, (2.) That, as he was dead to the law, so he was alive unto God through Jesus Christ (Gal. 2:20): I am crucified with Christ, etc. And here in his own person he gives us an excellent description of the mysterious life of a believer. [1.] He is crucified, and yet he lives; the old man is crucified (Rom. 6:6), but the new man is living; he is dead to the world, and dead to the law, and yet alive to God and Christ; sin is mortified, and grace quickened. [2.] He lives, and yet not he. This is strange: I live, and yet not I; he lives in the exercise of grace; he has the comforts and the triumphs of grace; and yet that grace is not from himself, but from another. Believers see themselves living in a state of dependence. [3.] He is crucified with Christ, and yet Christ lives in him; this results from his mystical union with Christ, by means of which he is interested in the death of Christ, so as by virtue of that to die unto sin; and yet interested in the life of Christ, so as by virtue of that to live unto God. [4.] He lives in the flesh, and yet lives by faith; to outward appearance he lives as other people do, his natural life is supported as others are; yet he has a higher and nobler principle that supports and actuates him, that of faith in Christ, and especially as eyeing the wonders of his love in giving himself for him. Hence it is that, though he lives in the flesh, yet he does not live after the flesh. Note, Those who have true faith live by that faith; and the great thing which faith fastens upon is Christ’s loving us and giving himself for us. The great evidence of Christ’s loving us is his giving himself for us; and this is that which we are chiefly concerned to mix faith with, in order to our living to him.

Lastly, The apostle concludes this discourse with acquainting us that by the doctrine of justification by faith in Christ, without the works of the law (which he asserted, and others opposed), he avoided two great difficulties, which the contrary opinion was loaded with:—1. That he did not frustrate the grace of God, which the doctrine of the justification by the works of the law did; for, as he argues (Rom. 11:6), If it be of works, it is no more of grace. 2. That he did not frustrate the death of Christ; whereas, if righteousness come by the law, then it must follow that Christ has died in vain; for, if we look for salvation by the law of Moses, then we render the death of Christ needless: for to what purpose should he be appointed to die, if we might have been saved without it.
